Minecraft Fire Alarm System

Main Panel

Four buttons that allow you to silence the horns (if you can call them that) but allows the strobes to continue flashing. In an actual alarm system, this is a feature that allows you to hunt down the offending pull station in peace and quiet.
Other buttons allow you to conduct a test or walk test, and reset the entire system.

And off...

Walk Test Time!

An indicator light turns on! (you didn't see that coming). A walk test allows you to go around your system and verifying that each pull station works. When you activate a pull station while the system is in walk test, the alarm only stays on until you reset the pull.
